Alexandre Becquart developed and enhanced security analytics features for the Azure/Azure-Sentinel repository, focusing on cross-cloud threat detection and rule governance over a three-month period. He implemented new analytic rules using Kusto Query Language and YAML to correlate threat intelligence with email events, detect AWS S3 object exfiltration, and improve EC2 startup script auditing. Alexandre standardized rule naming conventions and refined packaging for AWS data connectors, streamlining deployment and maintenance. His work emphasized data quality, improved alert accuracy, and expanded monitoring coverage across AWS and Azure environments, demonstrating depth in cloud security engineering and a methodical approach to SIEM rule development and integration.
October 2025: Azure Sentinel AWS analytics rules enhancements and a new S3 object exfiltration detection rule. Added a new analytics rule file to detect S3 object exfiltration by anonymous users in AWS environments and refined existing AWS analytics rules (S3 exfiltration, ECR image scanning, privilege escalation) for improved accuracy and clarity. This work emphasizes expanding cross-cloud threat detection coverage and rule reliability within the Azure Sentinel ecosystem.

In August 2025, Azure/Azure-Sentinel delivered targeted feature work to enhance threat detection, security analytics, and rule governance. Two key features were implemented: - Threat Intelligence: TI map IP entity to EmailEvents analytic rule, introducing a new correlation rule to strengthen detection and standardizing analytic rule file names by renaming three existing rules to include the .yaml extension. Commits: 654076ded5f436dd4042ac69d4b4ffa992b64077. - EC2 startup script analytics: parse UserName from UserIdentityPrincipalid, providing richer context for security events and improving auditing capabilities. Commit: 690932c08c08238599349dc6260086fe5958acff. While no explicit major bugs are listed in the provided data, the work improves visibility, governance, and incident response readiness by standardizing rule naming and enriching data captured in analytics.
